[koichiro]

:upper_limit :lower_limit のargsが空文字でわたってくるのが問題っぽい

[koichiro]

graphメソッドにわたってくるargsのupper_limitが空文字でくる

11:53:59 web.1     | args
11:53:59 web.1     | {:service_name=>"socialgame", :section_name=>"member", :graph_name=>"register", :complex=>nil, :from=>"2016/03/18 11:53:55", :to=>"2016/03/26 11:53:55", :width=>390, :height=>110, :graphonly=>false, :logarithmic=>false, :background_color=>"f3f3f3", :canvas_color=>"ffffff", :font_color=>"000000", :frame_color=>"000000", :axis_color=>"000000", :shadea_color=>"cfcfcf", :shadeb_color=>"9e9e9e", :border=>3, :legend=>true, :notitle=>false, :xgrid=>"", :ygrid=>"", :upper_limit=>"", :lower_limit=>"", :rigid=>false, :sumup=>false, :step=>nil, :cf=>"AVERAGE"}

結果としてrrdoptionsに-uオプション２つ含まれて２個目の-uオプションの値が空文字になる> "-u", ""

11:53:59 web.1     | rrdoptions
11:53:59 web.1     | ["/var/folders/_0/81x3y3ws5x985sy3108m8dzm0000gn/T/20160326-11405-1d3ktud.png", "-w", 390, "-h", 110, "-a", "PNG", "-l", 0, "-u", 2, "-x", "HOUR:1:HOUR:2:HOUR:2:0:%H", "-s", -118800, "-e", "now", "--slope-mode", "--disable-rrdtool-tag", "--color", "BACK#F3F3F3", "--color", "CANVAS#FFFFFF", "--color", "FONT#000000", "--color", "FRAME#000000", "--color", "AXIS#000000", "--color", "SHADEA#CFCFCF", "--color", "SHADEB#9E9E9E", "--border", "3", "-t", "Day (5min avg)", "--font", "AXIS:8:", "--font", "LEGEND:8:", "-u", "", "-l", "", "DEF:num0t=./data/c4ca4238a0b923820dcc509a6f75849b.rrd:num:AVERAGE", "CDEF:num0=num0t,-1000000000,1000000000000000,LIMIT,1,*", "AREA:num0#33cc66:register ", "GPRINT:num0:LAST:Cur\\: %4.1lf%s", "GPRINT:num0:AVERAGE:Avg\\: %4.1lf%s", "GPRINT:num0:MAX:Max\\: %4.1lf%s", "GPRINT:num0:MIN:Min\\: %4.1lf%s\\l", "VDEF:num0cur=num0,LAST", "PRINT:num0cur:%.8lf", "VDEF:num0avg=num0,AVERAGE", "PRINT:num0avg:%.8lf", "VDEF:num0max=num0,MAXIMUM", "PRINT:num0max:%.8lf", "VDEF:num0min=num0,MINIMUM", "PRINT:num0min:%.8lf"]

[koichiro]

rrd.rbにある upper_limit のデフォルト値は２になっている。

  rrdoptions = [
      tmpfile.path,
      '-w', width,
      '-h', height,
      '-a', 'PNG',
      '-l', 0, #minimum
      '-u', 2, #maximum

一方 web.rb のデフォルト値は空文字になってる。

graph_rendering_request_spec = {
...
    upper_limit: { default: '' },
    lower_limit: { default: '' },
...

空文字のweb.rbが有効になっているのでweb.rb側でも２をデフォルトにすればよさそう。

[koichiro]

web.rbのグラフ表示のデフォルト値を数値すると表示できた
